PROBLEM TO BE SOLVED: To provide a technique in a distribution panel including a primary feeding device such as a primary feeding breaker in which a length of a primary feeding terminal block in a longer direction arranged in a primary side of a trunk breaker can be shorten.SOLUTION: A primary feeding terminal block 1 includes a connection bar which is connected with a primary side of a multipole trunk breaker 3. The connection bar 4 comprises: a power source connection plate part 7 including a primary breaker connection part 24 to which a primary side terminal of the trunk breaker 3 is connected; a primary feeding device connection plate part 8 to which a plug-in type primary feeding device 2 is connected; and a coupling plate part 9 by which the power source connection plate part 7 is connected with the primary feeding device connection plate part 8. Respective plate surfaces on the power source connection plate parts 7 of respective poles are parallelly arranged in parallel with a substrate of a distribution panel on which the primary feeding terminal block 1 is disposed. At least one coupling plate part 9 of one pole includes vertical coupling parts 14, 15, 16, 18, 19 arranged in the space formed between the respective power source connection plate parts and the substrate while the plate surface thereof is perpendicular to the substrate of the distribution panel. |
